Case File #509 | Sound Detective Reading
The forest was thick with a heavy, damp fog as Elias began his search. He didn’t enjoy being out so late, but he was loyal to his team. They needed to find the source of the strange sound that had caused the birds to fly off in a sudden flash.
He stepped carefully over a wet log, making sure not to stomp on the delicate moss. A thin layer of frost had begun to form on the leaves, making the ground slippery. Elias stopped to quench his thirst with a sip from his water bottle. In the distance, he heard the low prowl of a stray wind through the trees.
Suddenly, he saw a movement in the shadows. He saw a frown on the face of his teammate who had just caught up to him. Something was moving near the edge of the clearing. Elias pulled out his notebook to sketch the shape he saw. The object didn't move like an animal; it seemed to bounce lightly as the wind caught it.
As the moon broke through the clouds, its light reflected off a metal coil sticking out from the dirt. Elias realized this was no monster—it was a piece of fallen machinery. He wiped the gloss of sweat from his forehead and headed back to camp.
